OMAHA, Neb. (AP) — A rural Nebraska woman who reported her gibbons were stolen is now being charged with keeping the endangered apes as pets.

Nancy Stephens, of Doniphan, was charged Monday in U.S. District Court in Omaha with violating the Endangered Species Act, which prohibits the transportation, shipment or receipt of endangered species.

Court documents allege Stephens violated the act in February 2011. She reported the theft of her primates, Caylee and Cody, in September 2013.

The Lee County Sheriff’s Office in Florida says deputies found Stephens’ gibbons during a traffic stop. The apes were placed in a Florida sanctuary, and their whereabouts are now unknown.

A plea hearing for Stephens is scheduled for May 26 in Lincoln. She couldn’t be reached for comment on the charges Monday.
